Patent CA-2067776-C (CA)
Title: Surgical instrument with input power transducer
Inventor: DODICK JACK MURRAY
IPC: A61M1/00
Filed: 1990-10-24
Granted: 2001-09-04
Abstract: A surgical instrument in the form of, for example, a two mm needle (10) has an open distal aspiration port (22, 22a, 36) for holding tissue to be fractured. An optical fiber (26) extends along the length of the needle and has its distal end positioned close to a metal target (24; 24A, 24a, 34). Pulses of laser energy are discharged from the distal end of the optical fiber to strike the tar-get. The target acts as a transducer converting the electromagnetic energy to mechanical shockwaves that are directed onto tissue in an operating zone adjacent to the aspiration port. The mechanical shockwaves cause the tissue to fracture and the tissue togeth-er with irrigating fluid is drawn out through an aspirating passageway (20). A  flexible tube (32) as the needle enhances access to various areas where tissue is to be fractured

Title: Wood preservation systems including halogenated tannin extracts
Inventor: LOTZ W ROBERT
IPC: B27K3/34
Filed: 1992-06-19
Granted: 1998-07-21
Abstract: The invention relates to wood preservation systems which employ impregnating agents comprising halogenated tannin extracts from plant species which are relatively more resistant to fungi, weathering, rotting, insect attack, etc. Materials contained within the tannin extracts are converted to halogenated substances which are absorbed by the wood species to be treaded. The halogenated extract materials can be used with or without other treatment agents (e.g., fixatives or metal salts). Bromine is the preferred halogen material, with optimum treatment occurring when the bromine concentration in the extract exceeds about 2% (most preferably, about 4-5%).

Abstract: An electronically controlled syringe system (14a) for connection to a balloon catheter or other balloon-type member and for automatically monitoring, displaying and recording inflation data when the syringe system is used to inflate the balloon of the catheter or other balloon-type member. A syringe (16) having a barrel (22) and a syringe plunger (24) is selectively operable to increase fluid pressure applied to the balloon catheter or other balloon member by sliding the plunger (24) further into the barrel (22). Positive pressure applied to the balloon catheter or member is released by withdrawing the syringe plunger (24) toward the rear of the barrel (22). A piezoresistive semiconductor transducer housed on the barrel (22) of the syringe (16) senses fluid pressure applied by the syringe. The electric signal output by the transducer is input to a controller (20a) where the signal is digitally processed so as to derive and record therefrom electronic data representing the magnitude of applied fluid pressure, and so as also to derive the length of time that fluid pressure is applied. The electronic data representing this information is automatically displayed and recorded. In one embodiment, the controller (20a) is also mounted onto the syringe barrel (22) to provide a digitally controlled inflation syringe system that is completely self-contained, and disposable.

Abstract: Apparatus  and  method  are  provided  for containing blood flashback during insertion of a guide wire into a blood vessel.   The apparatus includes  a barrel having a  flashback chamber. An  inner  cannula  in  the  flashback  chamber communicates with an inserter needle mounted on the  barrel.    The inner  cannula  includes  an aperture   communicating   with   the   flashback chamber.    A  porous  vent  plug  is  slidably disposed   in   the   chamber   in   fluid-tight engagement with both the barrel  and the inner cannula.    The vent  plug  can be  slid  from  a proximal  position  where  the  aperture  in the inner cannula is exposed to a distal position where  the  aperture  in  the  inner  cannula  is blocked.   A guide wire  in  the  inner  cannula blocks blood flow.  The vent plug and the guide wire are retained proximally of the aperture in the  inner  cannula  until  blood  flashback  is observed.     The  vent  plug  is  then  axially advanced to cover the aperture and stop further blood flow.  The guide wire can then be advanced safely into the blood vessel.

Abstract: Conceived with the human-engineering objective of overcoming Repetitive Motion Injuries such as Carpal Tun-nel Syndrome. The solution, a system comprising a split-keyboard spaced laterally into vertically arranged co-opera-tive keypad halves (24, 24') optimally enabling the user to sit with the lightweight portable keyboard (23, 23') assembly laying directly upon their lap. Traditional keyboards orient operator's hands inducing a wrist-twisting, arm-extending stress while the stress-free ergonomic bodily position herein liberates one from such trauma by reorientation of the hands and arms to a non-pronated, unextended position.      This correction involves the upper-arm draping naturally down from the shoulder with the forearm set at a relaxed forward projecting right-angle, placing the Carpalligaments. of one's wrists in a non-torqued, neutral position. Because weight of the extended hand/forearm is borne comfortably upon the narrow side (hypothenar-eminence) of the hand, this newly identified reorientation requires no appreciable musculature effort to maintain. The arrangement of keypad controls, with transverse adjustability to user's physique, serves to ameliorate onset occurrence of keyboard associat-ed RMI-diseases. Utilizing visual-reference mirrors (22, 22') adjustable to a user's eye, enables them to readily reference any key-indicia or tracking-mouse hemisphere (34, 34') via conveni-ence of natural mirror-image/reverse-compensated character notation. The system universally interfaces with ordinary electronic keyboard connections, and employs a conventional (albeit split) Qwerty keyboard. It is likewise adaptable to other keyboard for-mats. Optical accommodation of an Accounting-panel (ten-key; with affixed visual-reference mirror (39) at the right or left of the keyboard-base, is achieved via a modularly invertible attachment upon either laterally extensible retractable-support member.

Abstract: An ultrasonic handpiece wherein the entire assembled handpiece may be sterilized with an ingress of the sterilizing fluid into the interior of the handpiece. The handpiece is formed with an elongated housing sleeve and a coil unit for establishing an alternating magnetic field located therein. The housing sleeve and coil unit is assembled such that crevices are formed between the ends of the housing sleeve and coil unit, thus allowing steam, chemicals and heat to pass in and out of the interior of the handpiece for more rapid and thorough sterilizing of the handpiece. Further, the coil unit is not potted to the housing sleeve in order to allow for different thermal coefficients of expansion between materials without the buildup of undue stress.
